SALESFORCE-PD1 Practice Test 14 — 15 Questions

Question 1

A developer is implementing navigation in a Lightning Experience app using the NavigationMixin service in a Lightning Web Component. The developer wants to navigate to a standard ListView for the Account object. What is the correct type to specify?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

type: 'standard__objectPage', attributes: { objectApiName: 'Account', actionName: 'list' }. NavigationMixin.Navigate uses standard page references where type is 'standard__objectPage' and actionName is 'list'.

Answer

type: 'standard__webPage', attributes: { url: '/lightning/o/Account/list' }

Answer

type: 'standard__recordPage', attributes: { objectApiName: 'Account', actionName: 'view' }

Answer

type: 'standard__namedPage', attributes: { pageName: 'accountList' }

Question 2

A developer needs to write a Batch Apex class that processes records and ensures atomicity per batch chunk. Which TWO statements are true regarding Database.Batchable execution and error handling? (Choose TWO.)

Accepted Answer

Using Database.DMLOptions or Database.insert(list, false) enables partial processing of records within a chunk without failing the entire batch.. Using Database.insert(records, false) allows partial success within a batch chunk, and state can be maintained across chunks if Database.Stateful is used.

Answer

Batch Apex chunks automatically roll back entirely if a single record fails, regardless of DML settings.

Answer

Batch Apex jobs cannot be monitored programmatically via Apex code.

Answer

The finish method executes before all execute chunks have completed.

Question 3

A developer is troubleshooting a Lightning Web Component where data returned from an Apex wire adapter needs to be mutated before being rendered. What is the correct pattern to handle this?

Accepted Answer

Create a shallow copy or clone of the wire data object in a getter or property assignment before mutation.. Data returned from an Apex wire adapter is immutable (read-only). To mutate it, you must create a shallow copy or clone of the object before making changes. This can be done in a getter or by assigning the copied data to a new property. This pattern ensures you do not attempt to modify the original wire data, which would cause an error.

Answer

Decorate the wire property with @api mutable to allow direct writes.

Answer

Use the eval() function to strip immutability constraints from the prototype chain.

Answer

Directly assign new properties to the object returned by the wire adapter property.

Question 4

A developer is building a Lightning Web Component and wants to define a property that can be set by a parent component. Which decorator is required?

Accepted Answer

@api. The @api decorator in Lightning Web Components marks a property or method as public, making it accessible to parent components. It is the required decorator for any property that a parent needs to set, and it also makes the property reactive. Without @api, the property is private and cannot be set from outside the component.

Answer

@track

Answer

@auraEnabled

Answer

@wire

Question 5

Which tag is used in Visualforce to output field labels and values dynamically based on sObject field definitions?

Accepted Answer

. renders field values with correct formatting and related labels.

Answer

<apex:field>

Answer

<apex:inputField>

Answer

<apex:outputText>

Question 6

Which TWO practices are considered best practices when writing Apex unit tests in Salesforce? (Choose two.)

Accepted Answer

Create all required test data within the test method or test setup method.. Using Test.startTest/stopTest and avoiding SeeAllData=true are essential Apex testing best practices.

Answer

Hardcode record IDs directly from the sandbox into assertions.

Answer

Query production records directly in every assertion to verify live system status.

Answer

Use @isTest(SeeAllData=true) on all test classes to ensure maximum compatibility with production data.

Question 7

What is a 'Change Set' used for?

Accepted Answer

To migrate metadata between related Orgs.. A Change Set is a Salesforce metadata deployment tool used to migrate customizations and code from one org to another, typically between related orgs such as sandbox and production. It packages metadata components like Apex classes, objects, and layouts for deployment.

Answer

To debug Apex code.

Answer

To backup user records.

Answer

To write Apex code.

Question 8

Which THREE actions can cause a governor limit exception during a poorly optimized trigger execution? (Choose three.)

Accepted Answer

Exceeding the maximum synchronous heap size of 6 MB by loading massive attachments into collections.. Option B is correct because Apex enforces a 6 MB synchronous heap limit, and loading large attachments or bulky data into collections can exceed that heap size and throw a LimitException. Option C is correct because performing DML inside a loop issues one DML statement per record, quickly breaching the 150 DML statement synchronous governor limit. Option E is correct because a SOQL query inside a loop over Trigger.new executes one query per record, exceeding the 100 synchronous SOQL query limit. Option A is not a governor-limit violation: calling a future method from a scheduled Apex execute method is allowed (scheduled Apex can call future methods), and it does not itself cause a limit exception. Option D is not a limit issue: Trigger.old is simply null/unavailable in an insert trigger, which is a runtime behavior rather than a governor limit exception.

Answer

Invoking a future method directly from a scheduled Apex class execute method.

Answer

Accessing Trigger.old in an insert trigger.

Question 9

Which TWO types of triggers can be defined in Apex? Choose 2 options.

Accepted Answer

after trigger. In Apex, the two supported trigger types are before triggers (option D) and after triggers (option A). A before trigger fires before records are saved to the database and is used to validate or modify field values on the incoming records, while an after trigger fires after records are committed and is used to access system-set fields like Id or to perform related-record DML. Apex does not support instead of triggers (option B), which exist in T-SQL for views; commit triggers (option C) are not an Apex construct; and validation triggers (option E) are not a trigger type—validation is handled by before triggers or validation rules.

Answer

instead of trigger

Answer

commit trigger

Answer

validation trigger

Question 10

A developer is building a Lightning Web Component and needs to execute code as soon as the component is inserted into the DOM. Which lifecycle hook should the developer use?

Accepted Answer

connectedCallback(). The connectedCallback() lifecycle hook is called when a component is inserted into the DOM. It is the appropriate place to execute initialization code that requires the component to be in the DOM, such as accessing elements or making network requests. It fires after the constructor but before rendering.

Answer

constructor()

Answer

disconnectedCallback()

Answer

renderedCallback()

Question 11

A developer is creating an Aura component that interacts with Salesforce data. Which TWO tags or features are valid in the Aura framework? (Choose TWO)

Accepted Answer

. Option A is correct because is a core Aura framework tag used to iterate over a collection such as v.items, rendering the body once per element with the specified var attribute. Option C is correct because is the standard Aura tag for declaring a component attribute, with name and type (e.g., String) being valid attributes. Option B is not valid Aura syntax; for:each and for:item are Lightning Web Components template directives, not Aura tags. Option D is not valid; lwc:databind is not an Aura or LWC feature, and Aura uses {!v.val} expressions without such a tag. Option E is not valid in an Aura component because import { LightningElement } from 'lwc' is the LWC base class import, used in JavaScript files of Lightning Web Components, not Aura.

Answer

Answer

<lwc:databind property="{!v.val}" />

Answer

import { LightningElement } from 'lwc';

Question 12

Which TWO methods are used to inspect sObject field metadata dynamically in Apex? Choose 2 options.

Accepted Answer

Schema.getGlobalDescribe(). SObjectType.getDescribe() and Schema.getGlobalDescribe() are used for inspecting schema metadata.

Answer

System.describeFields()

Answer

Object.inspect()

Answer

Database.getMetadata()

Question 13

A developer wants to retrieve up to 5 recently viewed records of any object type using SOSL. Which SOSL clause specifies the maximum number of records to return?

Accepted Answer

LIMIT 5. SOSL search results can be limited using the LIMIT clause at the end of the query statement.

Answer

TOP 5

Answer

MAX 5

Answer

ROWS 5

Question 14

Which THREE collections are available in Apex? (Choose three.)

Accepted Answer

Set. Apex provides three built-in collection types: List, Set, and Map.

Answer

Queue

Answer

Table

Question 15

An architect is designing an automation solution and wants to decide between a Record-Triggered Flow and an Apex Trigger. Which scenario heavily favors choosing an Apex Trigger?

Accepted Answer

Performing sequential HTTP callouts and complex JSON parsing in response to record inserts. Complex integrations, callouts, and heavy algorithmic processing across multiple disparate objects often necessitate Apex triggers over declarative flows.

Answer

Creating a task for the record owner upon lead conversion

Answer

Updating a field on a related parent record when a child record is created

Answer

Sending a standard email alert when a picklist value changes
